The contemporary form of the Stratco Outback Curved Roof Carport, Verandah or Patio will add value and impart a sense of style and sophistication to your home. The smooth, clean lines of the curved roofing form a graceful canopy over any outdoor area.
The Stratco Outback Curved Roof is available as a freestanding unit or attached to your home.
When combined with flat roofing or pergola sections it becomes part of a system, with the elegant curved roof forming the central feature of the design.
Available in either Multispan or Clearspan designs, the Stratco Outback Curved Roof can span up to 6.6 metres wide in either style.
The Outback Multispan Curved Roof has purlins that are placed over the rafters in the roof.
These purlins support your choice of cladding:
The corrugated steel is supplied pre-curved to the required radius for easy installation.
The Outback Clearspan Curved Roof minimises beams and rafters by using Outback Deck.
Outback Deck is a very strong material that does not need extra purlins to support it. This leaves the roof area clean and uncluttered with a ceiling-like appearance from beneath.
Outback Rooflites are also available to supply natural filtered light when Outback Deck is used in Clearspan designs.

Components

For Non-Cyclonic Areas
Two 12 x 20mm self drilling screws per pan at each support and two 3.2mm sealed aluminium rivets per pan at the back channel. If decking runs parallel to the back channel, secure to channel with rivets at maximum 200mm centres. All screws are to have neoprene washers.
For Cyclonic Areas
Three 12 x 20mm self drilling screws per pan at each support. For deck spans less than 3600mm, two self drilling screws per pan are to be used on fascia beam. Three 4.8mm sealed aluminium rivets per pan (or 150mm centres if sheets are parallel) to be used at the back channel. All screws are to have neoprene washers.

Design Considerations
Gable/Curved Units Attached Between a Flat Unit & an Existing Structure
Gable/Curved Units which are attached between a Flat Unit (excluding pergolas) and an existing house, shall only be considered attached if the Gable/Curved Unit is attached to the existing house (C) for its full length (L) and the longest side of the combined unit (B) does not exceed twice the gable/curved length (L). The Flat Unit in this case can be considered attached. This style requires all columns to be embedded into footings.
Gable/Curved Units Attached to Flat Unit One or Both Sides
Gable/Curved Units which are attached one or both sides to Flat Units, (excluding pergolas) must be attached to an existing house for at least 75% of the gable/curved opening length (O) to be considered attached. Flat Unit/s must be deemed attached as detailed in the Flat Unit section below to allow the Gable/Curved Unit to be considered attached.
Gable/Curved Units are considered attached both sides if both Flat 1 and 2 comply with attachment rules for Flat Units as detailed below. Gable/Curved Units are considered attached one side if only one Flat Unit exists and it complies with the attachment rules for Flat Units as detailed below.
Flat Units
A Verandah, Patio, Carport or Pergola is deemed to be freestanding unless it is attached to an existing house (C) for at least 75% of the length of its shortest side (A), and its longest side (B) does not exceed twice the length of its shortest side.
Design Options
When designing an Outback, consideration should be given to both roof sheet direction, and the orientation of any openings and overhangs involved. These are often determined by appearance and drainage requirements. The following shows some of the normal options used.
Attached to Flat Unit One Side & Wall or Fascia One End
Attached Both Sides to Flat Unit & Wall or Fascia Opposite Side
Attached to Flat Unit Both Sides & Wall or Fascia One End
